• The executive summary states that the level of investigation is G2 & G3 .
•  Resource estimation of the upper band of Bayyaram gutta (G2 stage): I. Present study (total tonnage of all grade) :0.1809 Ml.Tonnes. II. As per Sarma and Chowdhary :3.27 Ml.Tonnes. Total :3.45 Ml.Tonnes
•  Summarized resource estimation of a ll blocks in G3 stage : 70.53 Ml.Tonnes. of exploration (total tonnage of all grades)
•  As per UNFC & IBM norms, the cut off for Hematite Ore is taken as > 45% Fe, the break­ up is as follows:
•  Upper band of Bayyara m gutta (G2 stage) :1.06 Ml. Tonnes.
•  Lower band of other blocks (G3 stage) : 9.74 Ml.Tonnes. Total : 10.80 Ml.Tonnes.
•  However, the occurrence of > 45% Fe is occurring at various levels with over burden ranging from 7 M. to 190 M.
• Thus, the GSI report proves that the estimated reserves of Iron Ore with cut off > 45°/o Fe is around 10.80 Million Tonnes whereas the requirement of Steel Authority of India Ltd. (SAIL) is 200 Million Tonnes
